That is a great feature. Unfortunately we are having some legal problems relating to the sent emails. Customers can always tell they did not receive the email. The log shows us the email was sent but it does not show how it was received by the receiving server. We were advised, although this will never be waterproof, to also send the email to one of our own inboxes. This way we have evidence that there was an actual email going out and in.
